In 5:27 it says "any kind of unique identifier" - but I assume it's only limited to numbers and not letters? just want to make sure.

Traditional arrays are indexed by numbers, but PHP's arrays are different. They are called "associative arrays." In other programming languages, it is often called dictionary or hash. Hence you can use numbers or strings.
